CARRIAGE-SPRING.

SPECIFICATION forming part of Letters Patent No. 681,093, dated August 20, 1901.

Application filed May 10, 1901.

citizen of the United States, residing at Amesbury, in the county of Essex and State of Massachusetts, have invented new and'useful Improvements in Carriage-Springs, of which the following is a specification.

Ate

This invention relates to improvements in carriage-springs for vehicles; and it relates to improved means for connecting the ends A of the leaf or elliptic springs, as will hereinafter be more fully shown and described, ref erence being had to the accompanying drawview seen from X in Fig. 3.

lngs, wherein- Figure 1 represents a side elevation of a Fig. 2 represents Fig. 3 represents a Fig. 4 represents a shown in Fig. 2. Fig. 5 represents an end Fig. 6 represents a detail perspective view of one end of the lower spring.

Similar letters refer to similar parts Wher- A ever they occur on the difierent parts of the drawings.

In Fig. 1, A and B represent, respectively, the upper and lower leaves of an elliptic or ii 1 leaf vehicle-spring, to which are respectively attached the additional leaf-springs a a a and Ab?) Z), as is usual in this kind'of carriagesprings.

At each end of the spring A is made a hooked lip A, adapted to receive the end A of the other spring B, as shown in Figs. 3 and j 4:. In the hooked end of the spring A is made 1 a slotted perforation A", through which is inserted a shankB', made integral with the end of the spring B, as shown in Figs. 4.- and 6.

i The said shank B is provided at its end with a hooked head or projection B. Figs. 4 and 6.) I

As shown most clearly in Fig. 6 of the drawings, the shanks B are of much less width than the spring B, and the ends of the latter when the headed shanks are inserted in the apertures A in the spring A are received and retained by thehooked lips A.

(Shown in I Thehook shaped heads 13" project through Serial No. 59,546. (No model.)

the a ertures A" and en a e or hook over I? s s the walls of the latter, as shown most clearly in Figs. 3 and4 of the drawings. The springs are thus doubly interlocked or hooked together at each end, the hooked lips A hooking over the ends of the spring B and the hook-shaped heads B" hooking over the walls of the apertures A" in the spring A. The two springs are thus very securely connected together in such manner as to effectually prevent their becoming detached from each other and also preventing one of said springs from moving laterally relative to the other due to the jolting of the vehicle or similar causes. Furthermore, in springs of this character When the springs are compressed and suddenly expand as the vehicle rebounds the spring B has a tendency to slip from out the hooked ends of the spring A; but in the present invention this is effectually prevented by the hook-shaped heads B, which engage the Walls of the apertures A in the spring A.

It is immaterial which of the springs is termed the upper or the lower one, as

the device may be reversed in position without departing from the essence of my invention.

What I wish to secure by Letters Patent and claim is-- The herein described elliptic carriage spring comprising an upper and a lower member, one of said members having hook-shaped ends adapted to receive the ends of the other member, and the latter provided at its ends with shanks terminating in hook shaped heads, said shanks passing through apertures in the said hook-shaped ends and the hookshaped head engaging the ends of the aper tured member, wherebythe hooked ends of each member engage and interlock with the ends of the other member, thereby providing a duplex connection betweenthe springs at each end of the latter, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit-
